Microtubules

Microtubules are found in flagella and cilia

Flagella and cilia consist of nine fused microtubule pairs surrounding a core of unpaired tubules.

At the base of every flagella and cilia there are nine fused microtubule triplets. 

There are two types of molecular motors:  dynein and kinesin

These motor proteins use ATP to change their conformation. 
This change in shape pushes the transport vesicles along the microtubule tracks.

Kinesin- Always towards positive side
Dynein- Always toward negative side

Centrioles lie just outside the cell nucleus and are made up of a fused triplets.
Microtubules extend from the centrioles.
They attach to chromosomes and pull them apart.
